Just to update:

by adding to cn=config :

olcLogLevel: Stats

or loglevel 256 to slapd.conf

and with -d 0

and no other change to rsyslog.conf nor to journal.conf

I get all my connections, LDAP operations, results logged via syslog to /var/log/slapd/slapd.conf

Thank you!!!

As a side note, I've encountered deadlocks on RHEL7 on extremely busy
systems when journald is integrated with syslog like this. It also has a
strong negative effect on performance. Whether the deadlock is RHEL7
specific or not is unknown.

When OpenLDAP 2.6 releases, syslog (and journald) can be bypassed entirely
and a purely local log file can be used, resulting in a significant
performance increase.
